#### Undergraduate difficulties: algebraic skills and mathematical comprehension.

(University of Canterbury. Mathematics and Statistics, 1999)

Many first year university students struggle with mathematics. Observations in senior mathematics classes in four New Zealand secondary schools highlighted potential undergraduate problems, especially with algebraic and ...

#### Mathematical models of pituitary corticotrophs and perifusion experiments

(University of Canterbury. Mathematics, 2000)

It is well known that stress is an unavoidable and potentially harmful fact of life. Indeed mental stress is becoming recognised as a predominant factor behind many illnesses and deaths in industrialised nations. However ...

#### Radial Basis Functions Applied to Integral Interpolation, Piecewise Surface Reconstruction and Animation Control

(University of Canterbury. Mathematics and Statistics, 2009)

This thesis describes theory and algorithms for use with Radial Basis Functions (RBFs), emphasising techniques motivated by three particular application areas.
In Part I, we apply RBFs to the problem of interpolating ...

#### A bifurcation analysis of a multi compartment plankton-zooplankton-nutrient interaction.

(University of Canterbury. Mathematics and Statistics, 2004)

This thesis concentrates on understanding the long term behaviour of a multi-compartment phytoplankton-zooplankton-nutrient interaction. A variable-yield model is considered, in which the rate of carbon uptake by phytoplankton ...

#### Modelling the Presence-Absence of Multiple Species

(University of Canterbury, 2016)

Predicting which species will be present (or absent) across a geographical region
remains one of the key problems in ecology. Numerous studies have suggested several
ecological forces that can determine species ...

#### Right orders in full linear rings

(University of Canterbury, 1971)

The thesis is a study of right orders in a (left) full linear ring Q = HomD(V,V), V a right vector space over a division ring D. Chapter I, as well as summarizing known results needed in the sequel, outlines the method of ...

#### Phylogenetic Networks that Display a Tree Twice

(University of Canterbury, 2016)

In the study of phylogenetics, which is the study of how forms of life evolve and relate to each
other, there is great scope for mathematics to get involved. One such study of phylogenetics
that currently employs ...

#### Some Basis Function Methods for Surface Approximation

(University of Canterbury. Mathematics and Statistics, 2012)

This thesis considers issues in surface reconstruction such as identifying approximation methods that work well for certain applications and developing efficient methods to compute and manipulate these approximations.
The ...

#### Direct Search Methods for Nonsmooth Problems using Global Optimization Techniques

(University of Canterbury. Mathematics and Statistics, 2010)

This thesis considers the practical problem of constrained and unconstrained local optimization. This subject has been well studied when the objective function f is assumed to smooth. However, nonsmooth problems occur ...

#### Building trees, hunting for trees, and comparing trees : theory and methods in phylogenetic analysis

(University of Canterbury. Mathematics and Statistics, 1997)

Phylogenetics is the study and identification of evolutionary patterns and structures in nature; this thesis explores the mathematics of these structures. The basic objects of study are the leaf labelled tree and its ...
